Air quality modeling and air pollutants/meteorology/climate interactions
대기질 모델링 및 대기오염물질/기상/기후 상호작용
We employ regional-scale atmospheric chemistry models (e.g., WRF-Chem and CMAQ models) and urban-scale models to investigate air quality and its interaction with local-/regional-scale meteorology and climate.

Urban canopy models and urban meteorology modeling
도시캐노피모형 및 도시기상 모델링
Urban canopy models (UCMs) parameterize various physical processes occurring in urban areas, which are not explicitly represented in regional- or climate-scale models. UCMs can be directly applied to urban greening strategies (e.g., planting trees) for climate change adaptation strategies.
